With that said, once you have some essentials and a weapon, the only thing that can kill you is another player. It doesn't matter if there are 15 zombies around you, they will never touch you if you keep strafing, shooting, strafing, and shooting. Of course, it is impossible for a human being to shoot a gun while walking, so you have to choose when to stop moving. Or run through a building, which are holy structures that prevent zombies from running and will aid in your escape. There's also the human wildlife for when you decide to leave your lair of supplies and guns, 90% of which have absolutely no way of attacking you. This is great for when you are angry at the world one day and want to kill tons of defenseless people for what is imagined to bring upon delicious rage.
